curl-win32.h: Enable Unix Domain Sockets based on the Windows SDK version

Microsoft added support for Unix Domain Sockets in Windows 10 1803
(RS4). Rather than expect the user to enable Unix Domain Sockets by
uncommenting the #define that was added in 0fd6221f we use the RS4
pre-processor variable that is present in newer versions of the
Windows SDK.

Closes #3939
